It has recently been proposed (Fowler, 1967, 1971) that the incentive value of novelty can be defined in terms of stimulus change. An experiment is reported which examines the relationship between changes in complexity and the consequent exploratory behavior. Following extended exposure to a midcomplexity stimulus, rats were allowed to choose between a stimulus change and the now familiar midcomplexity stimulus. For some Ss the change was to a stimulus of higher complexity, and for others the change was to a lower complexity stimulus. The results suggest that physical stimulus changes to a stimulus of greater complexity is a more effective novel stimulus than physical stimulus changes to lesser complexity, although both changes may function as incentives. 相似文献

Previous studies have reported, but not explained, the reason for a robust association between reading achievement and antisocial behavior. This association was investigated using the Environmental Risk (E-Risk) Longitudinal Twin Study, a nationally representative 1994-1995 birth cohort of 5- and 7-year-olds. Results showed that the association resulted primarily from environmental factors common to both reading and antisocial behavior and was stronger in boys. Environmental factors also explained the relation between reading disability and conduct disorder. Leading candidate environmental risk factors weakly mediated the association. For boys the best explanation was a reciprocal causation model: poor reading led to antisocial behavior, and vice versa. In contrast, the relation between reading achievement and attention deficit hyperactivity disorder was best explained by common genetic influences. 相似文献

OBJECTIVE: The current study examined the prevalence and characteristics of childhood sexual abuse in a jailed-based population. METHODOLOGY: A retrospective, self-reported survey was administered over an 8-week period to a random sample of 100 men who were incarcerated in a county jail in Southeastern Texas. The survey included questions about childhood sexual experiences before and after puberty, drug history and use, and sexual risk-taking behaviors. RESULTS: Of the 100 male inmates who participated in this study, 59% reported experiencing some form of sexual abuse before puberty, and all such instances occurred before or at the age of 13 years. The first episode of childhood sexual abuse began at an average age of 9.6 years (SD = 2.4), and ended at an average age of 13.0 years (SD = 2.3). Kissing and touching without intercourse (64%) was the common pattern of sexual abuse experience reported. The total number of perpetrators was 165, with 10% male and 90% female. Friends (n = 72) and family (n = 56) were the most frequent perpetrators. CONCLUSION: Childhood sexual abuse may be more prevalent among inmates than among males in the general population. These results show a high percentage of inmates who report a history of childhood sexual abuse; this rate is higher than those reported by other studies for incarcerated males. The findings support the belief held by professionals in the criminal justice field that a significant number of incarcerated males may have been victims of sexual abuse. 相似文献

Governing boards have a long tradition and prominent role in U.S. higher education. The diversity of institutional types, and thus governing boards, represents a multifaceted tapestry of functions, roles, and responsibilities. This paper will attempt to define the parameters of public higher education governing boards in the USA and offer critical insights into their degree of effectiveness. It is the author’s position that both positive and negative lessons can be learned through an examination of these public governing boards in the USA. The recent emergence of university boards in Europe is examined and their characteristics are compared against the characteristics of public and private boards in the USA. 相似文献

Recent research efforts (Schmidt et al. in The preparation gap: teacher education for middle school mathematics in six countries, MSU Center for Research in Mathematics and Science Education, 2007) demonstrate that teacher development programs in high-performing countries offer experiences that are designed to develop both mathematical knowledge and pedagogical knowledge. However, identifying the nature of the mathematical knowledge and the pedagogical content knowledge (PCK) required for effective teaching remains elusive (Ball et al. in J Teacher Educ 59:389–407, 2008). Building on the initial conceptual framework of Magnusson et al. (Examining pedagogical content knowledge, Kluwer, Dordrecht, pp 95–132, 1999), we examined the PCK development for two beginning middle and secondary mathematics teachers in an alternative certification program. The PCK development of these two individuals varied due to their focus on developing particular aspects of their PCK, with one individual focusing on assessment and student understanding, and the other individual focusing on curricular knowledge. Our findings indicate that these individuals privileged particular aspects of their knowledge, leading to differences in their PCK development. This study provides insight into the specific aspects of PCK that developed through the course of actual instructional practice, providing a lens for future research in this area. 相似文献

Improving forestry education through participatory curriculum development: A case study from Vietnam
Peter Taylor 《The Journal of Agricultural Education and Extension》2013,19(2):93-104
Abstract As agriculture and forestry practices change in different contexts, new requirements emerge for the development of education programmes. In forestry education there is a need for a shift of focus from technology towards an interdisciplinary approach based on a new range of knowledge, skills and attitudes, and drawing on new concepts of knowledge and learning. Increased participation of stakeholders in the forestry education process seems essential for this shift to take place, leading to greater empowerment, commitment, and more effective learning. This paper presents a case study of the Social Forestry Support Programme in Vietnam, in which participatory curriculum development (PCD) plays a fundamental part. Beginning with stakeholder identification and analysis, PCD provides an overall framework for educational development. Recognising constraints associated with the process, the paper describes strategies aimed at capacity building, management of stakeholder involvement, and planning and evaluation. As different stakeholders learn to learn together through discourse and interaction, the chances of sustainable outcomes from the PCD process should be improved. The dynamic and flexible nature of PCD suggests that there is considerable potential for its adaptation and application in a range of different contexts. 相似文献
